AT: Geometric

I didn't want to computer generate something geometric as I once again attempt something for abstract Thursday. I couldn't find my protractor so I settled for some graph paper, a pen and a ruler.  It's a pretty decent optical illusion among other things.

I love mathematics and geometry is at the top of the list. It was my favorite course of study and my favorite unit to teach.

The only shapes I drew were four interconnected isosceles triangles. If you would like to challenge yourself, how many of the following can you find?
1. isosceles triangles
2. equilateral triangles
3. squares
4. quadrilaterals (other than squares)
5. other convex polygons
...and how about line segments?

Don't look to me for answers. I have no idea.   :-)
